pinch force data
Description
151 measurements of pinch force during 20 replications with time from start of measurement.
Usage
pinch
pinchraw
pinchtime
Format
- pinch, pinchraw
-
Matrices of dimension c(151, 20) = 20 replications of measuring pinch force every 2 milliseconds for 300 milliseconds. The original data included 300 observations.
pinchraw
consists of the first 151 of the 300 observations.pinch
selected 151 observations so the maximum of each curve occurred at 0.076 seconds. - pinchtime
-
time in seconds from the start = seq(0, 0.3, 151) = every 2 milliseconds.
Details
Measurements every 2 milliseconds.
